Hello!
 
I'am dealing with chiller performance curves. And so once upon a time I had find the following informations about the calaculation in energyplus:
 
(1) FullLoadCoolingCapacity = ChillerCapFTemp * Reference Capacity
 
(2) FullLoadEIR = ChillerEIRFTemp * (1/Reference COP)
 
(3) PartLoadEIR = ChillerEIRFPLR * (1/Reference COP) * ChillerEIRFTemp
 
I' dont know wherefrom I got the informations. In the documentation i do not found this informations.
Is there anybody who can confirm the calculation and have a soruce for the calculations?
 
Best regards,
Alex

The engineering documentation for Chillers and other HVAC equipment lives in the Engineering Reference, which is installed with EnergyPlus (C:\EnergyPlusV8-2-0\Documentation\EngineeringReference.pdf).  Here is a link to that same documentation online (scroll down a little to see the equations you posted).
